As herewith partl-ularly shown,the im-' in a lock 11 disposed in asuitable cavity 12 provided in the free edge portion 13 of a door 14,and which is arranged to be oper-.

ated from the inner side of the door by'means of a knob 15, and from theouter-side of the door b'y'means of a thumb latch 16. The

bolt 17 of the lock is arranged to'normally extend. from the outer endof a bolt casing 18 mounted in the door edge face 19, such I casingbeing provided adjacent the point of emergenge o the bolt therefrom witha. flange 21 whereby it may beiixed to the door edge 19, it being notedthat-the flange 21 is also arranged to conceal the mouth of the portionof the cavity 12 which extends to the.

forward end of the latch plate 22 is perfo rated as at 24 for'thesliding reception of a 'shankI2'6 extending-inwardly from the bolt,.

such s hank being provided at its inner ex-' I tremity with an enlargedhead 27 which is arrangedto limit the outward movement of the bolt shankthrough the opening 24. A

compression spring 28 is disposed about the shank 26 and betweentheinner end of'the bolt head and the outer end of the latch plate 22whereby the bolt is arranged to be normally held extended from the latchplate for retraction therewith, and at the same time may be retracted'independently Journaled inthe casing 18 to extend-horizontallytherethrough is a latch actuator 29 having extending therefromintermediate the casingwalls an arm 31 arranged for engagement with thelatch plate 22 in such manner that a rotation of the actuator from thenormal position shown in Figure 5 will effect a retractive displacementof the latch plate. Preferably, and as shownthe actuator arm 31 isarranged for engagement with the latch plate both at the upper and lowersides thereof whereby a rotation of the actuator in either possibledirection may retract the latch plate.

Extending axially through theactuator is a perforation 32 in which aspindle 33 is arranged to be disposed. Means are provided for preventinga rotation of the spindle in the perforation and as here showntheperforation and spindle are of like and polygonal cross section wherebythe spindle may be utilized for effecting a rotation of the actuator.The spindle 33, it is noted, is arranged to extend through the actuator29 and protrudes from the door only at the inner side thereof. Arrangedfor mounting at and against the inner side surface of the door is aplate ,34 having rotatably journaled therein a sleeve 36 arranged toslidably receive the spindle 33 therethrough for rotation therewithashere shown, the spindle and the bore of the sleeve are of like polygonalcross-section. The knob 15, it is noted, is mounted at the inner end ofthe spindle for effecting a rotation thereof. .An escutcheon plate 38 isprovided, such plate being arranged to conceal the plate 34. It will benoted that a certain amount of axial reciprocation of the spindle 33 ispermitted and that such spindle provides the sole actuating means forthe latch plate 22; p

Means are provided for effecting a withdrawal of the bolt 17 from theouter side of the door independently of the spindle 33,

- and as here shown such means are carried on a plate member 39 arrangedfor disposal at and against the outer side surface of the door. It willnow be noted that the plates 34 and 39 are notsecured directly to thedoor but are arranged to be fixed in proper position on the door byclamping the door between them. Extending inwardly from the outer plate39 toward the plate 34 are posts 41 provided with threaded axial boresfor the reception of clamp screws-42, which screws are disposed throughsuitable perforations provided in the plate 34 opposite the posts 41whereby the plates 34 and 39 may be forcibly drawn together against theopposite sides of a door for fixedly securing them to the door of thelatch plate.

in proper relation to the bolt mechanism and the lock cavity. v

A withdrawal of the bolt from the outer side of the door is, in thepresent embodiment, arranged to be eflected by means of the thumb latch16. As shown, the thumb latch 16 is of a usual lever form and isfulcrumed in an outer escutcheon plate 44 enclosing and carried by theplate 39, with an inner end portion 46 thereof extending inwardlythrough a vertically. directed slot 47 in the plate 39. Mounted on theinner side of the plate 39 for movement in a plane parallel to the plateis a lever' 48, such lever having an end thereof pivotally secured tothe plate I 39, an intermediate portion 49 generally horizontal andbearing on the upper side of the thumb latch portion 46, and a free endportion 51 arranged for engagement with one arm 52 of a bell crank lever53 carried on the plate 39 for rotation about an axis perpendicular tosaid plate. The other arm 54 of the bell crank lever 53 carries a pin56. protruding inwardl therefrom in a direction parallel to the pivotalaxis of the bell crank lever, While protruding inwardly from the boltshank head 27 through the boltcasing 18 is a headed pivot pin 57 whichis arranged for reciprocation with the bolt, it being noted that thepivotal point of the bell crank lever 53 and the pivot pin 57 arehorizontally offset by an appreciable distance. Mounted on andconnecting the pins 56 and 57 is a link 58, such link being arrangedwhen the bell crank lever 53 is rocked from its normal position toeffect a withdrawal of the bolt 17. In this manner, a withdrawal'of thelatch bolt is arranged to be effected by means of the thumb latch 16independently of any actuation of the spindle 33 or the latch plate 22.

Preferably, and as shown, the 'pin 56 is cylindrical and is slidablyengaged in an eye provided at the cooperating end of the link 58. Inthis manner the link may be variably engaged along the pin 56 when theplates 34 and 39 engage doors of different thickness between them, sothat the one look structuremay be installed on doors of differentthickness without alteration or special fitting.- It will of course beobvious that the latch bolt and its casing are supported independentlyof the various lock operating mechanisms provided, the latter beingsupported by and between the plates 34, and 39. The spindle v33, it willnow be noted, is provided at the outer, and free, end thereof, with astop member 59, such member being arranged to be disposed in the path ofmovement of the lever 48 when the spindle is in its axially outwardposition withrespect to the inner side of the door to prevent anoperative displacement of said lever. here shown, the stop member 59 isreciprocable in a like shaped bore 61 provided in I .8' plate'meniber 62fixed the outer lock.

plate 39in inwardly spaced relation thererom' and between it and'the'bolt casing 18. Preferably, the stop member 59 is swivelled to thespindle and is'a'rranged to maintain] a non-rotatable engagement in thebore 61 at and between its twoextreme positions.

I Mounted on the I plate 62 is aspring pressed detent 63, suchetent beinengageable in a Vi-shaped-notch 64'provi ed in the side t'ent 63 withthe stop mem r 59 being such that it may be displaced upon the exertionof a slight, but marked, axial force onthe- 'spi-ndle' 33. In thismanner, the stop is arranged to be positively and releasably held ineither one of its set positions; As here A shown, the plate member 62 isrovided with integral posts 65. which 'are'rlvetedin suitableperforations provided in the outer clampplate 39. It will nowbe clearthat the spindle 33is operable at all times to retract the latch boltand that the rotative operation thereof for retracting the bolt does notefi'ect the setting of the stop 59.

'As is usual with locks for outside doors,

key cont-rolled means operable from the outsi e of the door are providedin the lock structure. Mounted in the clamp plate 39 and its associatedescutcheomplate 44 to extend therethrough is a tumbler barrel'casing 66,such casing carrying a key controlled tumbler barrel .67 of a usualstructure. The inner .end of the barrel '67 provides the pivotal.mounting for the bell crank lever 53, the latter being swivelledthereto. As here shown, the bell crank lever 53 is swivelled'to apolygonal block 68, which block is in turn arranged to be secured in asocket 69 formed in a member 71 fixedjo the inner end of the tumblerbarrel and providing an arm'72. The, arm 72, it will be noted, nor

mally lies operatively against and behind.

a pin 73 extending outwardly from the bell crank lever arm 54' and infront of and against a stop pin 74 carried by the casing 66; Means arepreferably. provided forresiliently urging the pin 73 of the bell cranklever 53 to be normally maintained against the arm '72, and the latterarm against the pin 74, and as here shown such means co'mprises atension spring 76 operativeliy connected between the lever 53 and a fixepoint on the plate 39. In this manner, the bell crank lever 53 isarranged to be independently rocked for withdrawing the lock bolt ingforcin I flat pointe instrument between t e-door edge either by anactuation. of the thumb latch 16 or the rotation of the tumbler barrel67.

As herewith particularly shown, the bolt 17 is particularly designed toprevent a wedgbac'k thereof throu h use of a the bolt, a spring81 beingtongue is held from and as usual istriker late disposed on the idoorjamb. According y, and as here shown, a portion 77 of the strikingface of the 'bolt is grovided on a tongue 78 hinged at its inner en totheremaining portion 79 of the bolt and normally extendinglongitudinally of provided for yieldinglyholding the tongue 8 inextendedpo- -'sit1on.'. The tongue 78 is arran ed to bedeflected into arecess 82' provide inthe bolt portion 79 whereby a continuous s'trikinstrface may be presented-- against the striking edge 83 of a strikingplate 84 as the bolt. moves against the latter. The striking plate 84 isprovided with spaced .perforations- 86 and 87 arrangedrespectively forthe'reception of the extremities of the bolt. ortions .78 and 79, thetongue portion 78 of t e bolt being arranged to enter the perforation 86only when and after the bolt portion 79 has partly entered theperforation 87. In this manner, aflat object inserted between the doorand striker plate 84- with the intention of wedging the same inwardlywould strike the surface of the tongue 7 8 atriiht angles, and since the-of the bolt is positively revented.

It willbe noted that t e door cavityv 12 for the rece tion of'those lockportions which are dis ose within the door space is arranged to e formedby providing intersecting eylindrical holes in the door, one of whichholes extends transversely through the door and the other of whichextends from the door edge 19. No other cavities are necessary, sincethe tumbler barrel and its casing are disposed in. line with thetransverse hole. In this manner, the necessary doorcavity for the lockmay be quickly and simply provided by the use of a carpenters bit and aminimum amount of fitting of the look to a dooris required.
